I-WiFi 7 (Wi-Fi 7) iyindinganiso yesizukulwane esilandelayo ye-Wi-Fi. Ihambelana ne-IEEE 802.11, i-Standard entsha ebukeziwe yeee 802.11be - Ukudlula okuphezulu kakhulu (eht) kuzodedelwa
I-Wi-Fi 7 yethula ubuchwepheshe obufana ne-320mhz Bandwidth, 4096-QAM, i-Multi-Link esebenza, kanye ne-Wi-Fi 7 ngokunamandla kunamandla amakhulu ku-Wi-Fi 7. I-Wi-Fi 7 kulindeleke ukuthi ixhase i-Presting of 30GBPS, cishe izikhathi ezintathu ze-Wi-Fi 6.

1. Kungani i-Wi-Fi 7?
Ngokuthuthukiswa kobuchwepheshe be-WLAN, imindeni namabhizinisi ancike kakhulu ku-Wi-Fi njengendlela esemqoka yokuthola inethiwekhi. Eminyakeni yamuva, izinhlelo ezintsha zinokusebenzisa okuphezulu nezidingo zokulibaziseka, njengevidiyo engu-4K ne-8K (izinga lokudlulisa lingafinyelela ku-20GBPS), i-Cloud I-Computer, njll kanye ne-latency.

Kuze kube manje, i-IEEE 802.11 I-Standard Organisation isizokhipha i-Standard Standard Revised Iee102.11be eht, okungukuthi i-Wi-Fi 7.
2. Ukukhishwa kwesikhathi se-Wi-Fi 7
I-IEEEE WEEE 802.1111111111111NE EHTSHIPT Group yasungulwa ngoMeyi 2019, kanye nokuthuthukiswa kwe-802.11be (i-Wi-Fi 7) kusaqhubeka. Lonke i-Protocol Standard lizodedelwa ekukhishweni okubili, futhi ukukhishwa1 kulindeleke ukuthi kukhishwe inguqulo yokuqala ku-2021 Draft1.0 kulindeleke ukuthi ikhiphe indinganiso ngasekupheleni kuka-2022; Ukukhishwa2 kulindeleke ukuthi kuqale ekuqaleni kwe-2022 futhi kuqedelwe ukukhishwa okujwayelekile ngasekupheleni kuka-2024.
3. I-Wi-Fi 7 vs Wi-Fi 6
Kususelwa ku-Wi-Fi 6 ejwayelekile, i-Wi-Fi 7 yethula ubuchwepheshe obusha obusha, ikakhulukazi kuboniswa ku:
4. Izici ezintsha ezisekelwa yi-Wi-Fi 7
Umgomo wephrothokholi ye-Wi-Fi 7 ukwandisa izinga lokufakelwa kwenethiwekhi ye-WLAN ku-30GBPS futhi unikeze iziqinisekiso zokufinyelela eziphansi ze-Latency. Ukuze uhlangabezane nale nhloso, lonke umthethonqubo wenze izinguquko ezihambisanayo ku-Phy ungqimba nongqimba lwe-Mac. Uma kuqhathaniswa nephrothokholi ye-Wi-Fi 6, ushintsho oluphambili lobuchwepheshe olulethwa yi-Wi-Fi 7 Protocol imi ngale ndlela elandelayo:
Ukusekelwa Okuphezulu 320mhz Bandwidth
I-spectrum engenalayisense kuma-band we-2.4GHz kanye ne-5GHz Frequency anqunyelwe futhi igcwele. Lapho i-Wi-Fi ekhona ye-Wi-Fi iqhuba izinhlelo zokusebenza ezivelayo ezifana ne-VR / AR, zizohlangana nakanjani inkinga yama-QOS aphansi. Ukuze uzuze inhloso yokusebenzisa okuphezulu kokungaphansi kwama-30gbps, i-Wi-Fi 7 izoqhubeka nokwethula i-bandwidy band bese ingeze ama-bandwidth aqhubekayo, kufaka phakathi okuqhubekayo kwe-bandwidth, okuqhubekayo kwe-160MHHZ, okuqhubekayo kwe-320 MHZ nokuqhubekayo 160 + 160mhz. (Uyemukelwa ukuze unake i-akhawunti esemthethweni: I-Network Engineer Aaron)
Sekela indlela ehlukahlukene
Ku-Wi-Fi 6, umsebenzisi ngamunye angathumela noma athole ozimele ku-Ru enikezwe ukuguquguquka okukhulu ukuguquguquka kwezinsizakusebenza ze-spectrum. Ukuxazulula le nkinga futhi uphinde uthuthukise ukusebenza kahle kwe-spectrum, i-Wi-Fi 7 ichaza indlela evumela i-rus eminingi ukuthi inikezwe umsebenzisi oyedwa. Vele, ukuze ulinganise ubunzima bokuqalisa ukusebenza kanye nokusetshenziswa kwe-spectrum, umthethonqubo wenze imikhawulo ethile kwinhlanganisela ye-Rus, okuyi-24) kuphela ihlanganiswe ne-rus enkulu, futhi ilingana ne-rus enkulu) ingahlanganiswa kuphela I-RUS enkulu enobukhulu ayivunyelwe ukuxutshwa.
Yethula i-oda eliphakeme le-4096-Qam Modulation Technology
Indlela ephakeme kakhulu yokushintshanaWi-fi 6ngu-1024-qam, lapho izimpawu zokushintshashintsha zithwala izingcezu eziyi-10. Ukuze uqhubeke ukhuphule izinga, i-Wi-Fi 7 izokwethula i-4096-QAM, ukuze izimpawu zokushintshana zithwala izingcezu eziyi-12. Ngaphansi kwe-encoding efanayo, i-Wi-Fi 7's 4096-Qam ingafinyelela ukukhuphuka kwesilinganiso esingu-20% ngokuqhathaniswa ne-Wi-Fi 624-QAM. (Uyemukelwa ukuze unake i-akhawunti esemthethweni: I-Network Engineer Aaron)
Yethula indlela yokuxhumanisa exhumanisayo ehlukahlukene
Ukuze uzuze ukusetshenziswa kahle kwayo yonke imithombo ye-spectrum etholakalayo, kunesidingo esiphuthumayo sokusungula ukuphathwa okusha kwe-spectrum, ukuxhumanisa kanye nezinqubo zokuhambisa ku-2.4 GHZ, 5 GHZ kanye ne-6 GHz. Iqembu elisebenzayo elichaze ubuchwepheshe obuhlobene nokuhlangene okuxhumeka okuningi, kufaka phakathi ukwakhiwa kwe-Mac kokuhlanganiswa okuxhunyaniswa kwama-multi-Link, ukufinyelela kwesiteshi esixhumanisa ama-multi-link kanye nezinye ubuchwepheshe obuhlobene.
Sekela ukusakazwa kwedatha okuningi, ukuthuthukiswa komsebenzi we-MIMO
E-Wi-Fi 7, inani lemifudlana yendawo lenyuke lisuka ku-8 kuye ku-16 ku-Wi-Fi 6, elingelona iqiniso elingaphezu kwamanani okudluliswa komhlaba. Ukusekela ukusakazwa kwedatha okuningi kuzoletha izici ezinamandla ngokwengeziwe, okusho ukuthi i-Mimo ehambisanayo, okusho ukuthi imifudlana yedatha engu-16 ingafakwa hhayi indawo eyodwa yokufinyelela, kepha ngamaphoyinti amaningi okufinyelela ngasikhathi sinye, okusho ukuthi ama-APS amaningi adinga ukusebenzisana.
Ukusekela Ukuhlelwa Komsebenzi Kwama-APS amaningi
Njengamanje, ngaphakathi kohlaka lwephrothokholi ye-802.11, empeleni akukho ukubambisana okuningi phakathi kwe-APS. Imisebenzi ejwayelekile ye-WLAN njengokuhleleka okuzenzakalelayo nokuzulazula okuhle izici ezichazwe ngumthengisi. Inhloso yokubambisana kwe-Inter-AP kuphela kuphela nokulungisa ukukhethwa kweziteshi kuphela, lungisa umthwalo phakathi kwama-APS, njll., Ukuze kufinyelelwe inhloso yokusetshenziswa okusebenzayo kanye nokwabiwa okulinganiselayo kwezinsizakusebenza zomsakazo zomsakazo. Ukuhlelwa okuhleliwe phakathi kwama-APS amaningi ku-Wi-Fi 7, kufaka phakathi ukuhlelwa okuhlanganisiwe phakathi kwamaseli esizinda sesikhathi nesikhathi sokuphazamiseka, kunganciphisa ngokuphumelelayo ukuphazamiseka phakathi kwama-APS, kuthuthukise kakhulu ukusetshenziswa kwezinsizakusebenza zomoya.
Kunezindlela eziningi zokuxhumanisa ukuhlelwa phakathi kwama-APS amaningi, kufaka phakathi i-C-ORDMA (ukuhlanganiswa okujwayelekile kwemvamisa okuhlanganisiwe), i-CSR (Ukuhlelwa kabusha kwe-CBR (ukuxhumeka okuhlanganisiwe), kanye ne-jxt (ukuhambisa okuhlanganisiwe).
5. Izimo zesicelo se-Wi-Fi 7
Izici ezintsha ezethulwe yi-Wi-Fi 7 zizokhulisa kakhulu isilinganiso sokudlulisa idatha futhi zinikeze nge-latency ephansi, futhi lezi zinzuzo zizoba wusizo ngokwengeziwe ekutholeni izinhlelo, ngokulandelayo:
- Ukusakazwa kwevidiyo
- Ingqungquthela yevidiyo / yezwi
- Imidlalo engenantambo
- Ukusebenzisana kwesikhathi sangempela
- I-Cloud / Edge Computing
- I-Intanethi Yezimboni Yezinto
- I-AR / VR
- telemedicine exhumanayo
